Subject: unexpected modification of a variable
From: Pascal.Courtois@nouvo.com (Pascal COURTOIS)

Hi,

Is there any way that a variable can be changed within a function without passing it by reference ?

I have a code like that:

function myfunction($var)
{
  
  <some code> 
  print_r($var); => prints $var which is an object
  anotherfunction($var);  // call by value
  print_r($var); => $var has changed

}


I thought that since there's no reference in any way to the variable it cannot be changed in the function. Am I wrong ?
